Baader Midband H-Alpha 35nm Filter - 2" Description

Baader's new H-Alpha passfilter enables high-contrast deep sky images of H-II regions (such as the North American Nebula). Its medium 35nm FWHM bandwidth is ideal for interline CCD cameras (like SBIG ST-2000/STL11000). The lower sensitivity of interline transfer CCDs benefits from the more efficient 35nm FWHM. The sharp bandpass and > 90% high efficiency coatings make the Baader H-Alpha filter superior to the common colored-glass based filters, all at a reasonable price.

The Baader H-Alpha filter shares the same outstanding features as all the other Baader imaging filters. Unmatched optical quality, and high efficiency hardened multicoatings result in the sharpest and highest contrast images.
